Two pistons—a TBM-exclusive design that balances powerful clamping force with even pad wear and weight savings. The two-piston layout promotes even pad wear and ensures smooth engagement.

No, the caliper is non-directional. You can mount it on either side of the vehicle, as long as the bleeder is the highest point on the caliper.

The F1/DR1 is available in 3.250" & 3.750” lug mount configurations. Be sure to select the right version based on your application.

The true cost of a product is not what it costs to buy it. The true cost is what it costs to “use it”. In the case of a brake caliper, this is measured by the capability factor, combined with the costs of the consumables factor.

The capability factor is a measurement of the life and resultant benefits. For example, our “Zero Drag” caliper so effectively reduces drag that far more horsepower is transmitted through the driveline. To replace that horsepower by making the engine more efficient would cost approximately 10 times as much.

Also, the biggest single cause of a “mid corner push” is caused by that brake drag. This affects the steering control and consequently, lap times negatively. In other words, steering control is enhanced, usable horsepower is enhanced, as is the overall driving control.

The consumables factor is the second point to consider. Due to the fact again of the “Zero Drag”, our calipers eliminate maintenance and brake pad wear by as much as 70 percent. This means that for every 3 sets of pads you now wear out, our calipers wear out 1 set.

Just consider the cost of those pads and the resultant overall cost of your system as a result. Just remember, we have not even assigned a value for the cost of your, or someone’s labor to replace them.

Zero Drag Technology is a proprietary design philosophy built into every TBM caliper. It ensures the brake pads fully release from the rotor after each stop—eliminating the subtle but costly friction that standard calipers often leave behind.

This isn’t just a feel-good feature. In racing, especially drag racing, every ounce of resistance costs you time, speed, and performance. TBM’s zero drag system ensures that your car rolls freer, cooler, and faster after every pass.

TBM offers multiple compound options specifically for the F1/DR1 but our most common brake pads for drag racing is:

6-1019

The pads are easily replaceable thanks to TBM’s quick-change design—no need to unbolt the caliper.

Yes. The F1/DR1 is designed for a specific rotor width—usually .280"- .375" depending on the kit. Always match rotor and caliper spacing properly to ensure pad-to-rotor alignment and performance.

Yes. TBM offers rebuild kits with seals and pistons. The caliper is designed for field-serviceability, making it ideal for racers who want to maintain their own equipment.

Use the ¼” bleeder screw at the top of the caliper, ensuring the caliper is mounted upright. Bleed until air bubbles are gone and the pedal is firm. TBM Brakes Xtreme 6 DOT5.1 fluid is recommended.

Yes—design, machined, assembled, and tested in Bradenton, Florida. TBM takes pride in American manufacturing and materials.
